Abstract An overview is given of neutron optics, aiming at a qualitative overview of the main concepts and components currently used for designing the optics of neutron instruments. The section on source optics shows the brightness curves of the Institu Laue-Langevin and ISIS cold sources and includes a short discussion of Liouville’s theorem. Neutron guides and supermirrors are dealt with in the section of reflection optics. In the diffraction optics section, I describe the concepts of mosaic and bent-perfect crystals, giving reference numbers for their performance and also attempting to cover some basic focusing concepts. There is a very short section on refractive optics, covering both materials and magentic lenses. The final section on polarisation optics is more detailed, partly because of the current rate of progress in the field and partly because it is an area with which the general reader may be less familiar.
